The tactical surveillance systems from Zistos include pole cameras and networkable surveillance cameras and both offer infrared thermal imaging options. The company's Dual Mode Thermal Camera (THC-50D) detects heat signatures through smoke, tear gas, and fog, and offers a 50-degree field of view. The Zistos Portable Network Surveillance Camera (PNSC) is a turn-key wireless solution for day and night field surveillance where no power or pre-existing network is available. It can also be used for radiological monitoring when equipped with the optional radiological alarm sensor.
